Presentation Transcript

  1. Exponential Regression

  2. Copy the table below your notebook and then graph the points

  3. Find an exponential function to fit the data. etc

  4. Exponential Regression • The relation between values of xand values of y, from which the value of y can be predicted for any value of x.

  5. Entering data into your TI 84

  6. CLEAR! ENTER!

  7. Step 1.  Enter the data in the calculator lists.  Place the data in L1 and L2.  STAT, #1Edit, type values into the lists

  8. Step 2. Prepare a scatter plot of the data.  Set up for the scatterplot. 2ndStatPlot- the first icon ChooseZOOM #9 ZoomStat.

  9. Step 3.  Have the calculator determine the line of best fit.STAT → CALC #4 LinReg(ax+b) Include the parameters L1, L2, Y1. (Y1 comes from  VARS → YVARS, #Function, Y1)

  10. Step 4.  Graph the line of best fit.  To get a predicted value within the window, hit TRACE, up arrow, and type the desired value.
